Rules are probably best described by using examples. This chapter contains numerous real world samples.

Show/Hide Manager Approval
You have a flow and the first form has a Section for manager approval. The Section is hidden by default. Here is an example of a rule that makes the section visible in the second step of the flow which is a linked activity assigned the manager role.
| Code Block |
|---|
if (form.load) {
var an = _data.getParameter ("flow.activity.name");
if (an === 'Manager' || an === 'VP'){
ManagerApproval.visible = true;
} else {
ManagerApproval.visible = false;
}

var Dms = new Date(da[0],da[1],da[2]);
if (Ams > Dms) {

} else {

Between Date

and Time
...
Here is a rule example to calculate the time difference between two Date/Time values in hours:minutes format :
| Code Block |
|---|
if (StartDateTime.value !== '' && EndDateTime.value !== '') {
var d = StartDateTime.value.split('-');
var d1 = d[2].split('T');
var t = d1[1].split('Z')[0];
var t1 = t.split(':');
var startDate = new Date(d[0],d[1],d1[0], t1[0], t1[1], t1[2]);
d = EndDateTime.value.split('-');
d1 = d[2].split('T');
t = d1[1].split('Z')[0];
var t1 = t.split(':');
var endDate = new Date(d[0],d[1],d1[0], t1[0], t1[1], t1[2]);
var diff = endDate.getTime() - startDate.getTime();
var hours = Math.floor(diff / 1000 / 60 / 60);
diff -= hours * 1000 * 60 * 60;
var minutes = Math.floor(diff / 1000 / 60);
TimeToComplete.value = (hours < 9 ? "0" : "") + hours + ":" + (minutes < 9 ? "0" : "") + minutes;
